Let’s say we have two empty stacks of integers, S1 and S2. Draw a picture of each stack after the following operations: pushStack(S1, 2); //push 2 into S1 pushStack(S1, 4); pushStack(S1, 6); pushStack(S1, 8); pushStack(S1, 10); pushStack(S1, 12); while ( !emptyStack(S1) ) { popStack(S1, x); //pop the top item of S1 and save it to variable x popStack(S1, x); pushStack(S2, x) }

2. A Markov chain is said to be doubly stochastic if both the rows and columns of the transition matrix sum to 1. Assume that the state space is {0, 1,....m}, and that the Markov chain is doubly stochastic and irreducible. Determine the stationary distribution T. (Hint: there are two approaches. One is to solve T P and ( 1 in general for doubly stochastic matrices. The other is to first solve a few examples, then make an educated guess...
